hello

I am setting up my apm 2.5.

but I van't find the radio callibration tab I have load the firmware to the board a few days before)

I need this for callibration and for reversing my elevons

I can't find the screen for that (see attached file, which screen I am searching for (I think))

How can I set the altitude and speed of the rtl function up?

thanks in advance
